Staffa HPC Motors


The enhanced variable displacement Staffa HPC series motor includes special low friction components combined with crankcase flushing flow to achieve increased shaft power.

The range of HPC motors extends from the HPC080 (1,600 cc/rev) to the HPC325 (5,326 cc/rev). There are 5 frame sizes in this product range – see the table below:

Motor TypeMax Torque @ 275 bar (Nm)Continuous Shaft Power with Flushing (kW) Continuous Shaft Power without Flushing (kW)
HPC080 6,630165138
HPC200 12,980261174
HPC325 22,440278189

Kawasaki “Staffa” high torque, low speed radial piston motors use hydrostatic balancing techniques to achieve high efficiency, combined with good breakout torque and smooth running capability. The HPC series dual displacement models have two pre-set displacements which can be chosen from a wide range to suit specific application requirements. The displacements are hydraulically selected by a directional control valve which can be remote mounted or directly on the motor. Motor displacement can be changed with ease when the motor is running.

These motors are also available in a continuously variable version using either hydro-mechanical or electro-hydraulic control methods. Other mounting options are available on request to
match many of the competitor interfaces.

Other features include:

  • Enhanced power performance
  • Increased speed
  • Improved starting and running efficiency
  • Increased back pressure capability
  • Speed sensing options
  • High torques at low speed
  • Smooth running
  • Wide range of displacements to suit specific applications
  • Displacement changes with ease when the motor is running
  • Various mounting options
